No posts following the overclocking of Ryzen 7 2700X - Asus Rog Strix X470-i Gaming
desperately seeking assistance, as I'm completely overwhelmed! I recently assembled this PC and it's functioning perfectly. I successfully overclocked the CPU with no issues and recently updated the BIOS using Asus EZ updates to take full advantage of new features for overclocking. I reached a speed of 4.35mhz, tested it in Cinebench and everything remained stable, achieving my best score. After rebooting, I ran another test in Cinebench but this time experienced a crash, then rebooted to the BIOS, slightly increased the voltage, and retested successfully. I was curious if lowering the voltage in the BIOS would help, but it seems I accidentally set it higher during my rush. In Cinebench it crashed again after rebooting, and now the PC won't post at all. I've performed numerous overclocks, and a crash usually resolves itself with a reboot, though sometimes it leads to a CMOS reset. Everything appears to power on normally, fans are running, power is reaching the motherboard, RAM and GPU are active, but it still doesn't post. I removed the RAM one at a time, replaced the GPU and reinserted it, tried using a separate VGA, but nothing worked. I even unplugged everything from the board, reset the CMOS, and reconnected everything, yet the issue persists. The Q LED sequence on the motherboard is orange, red for CPU, yellow for RAM, then flickers white for the VGA, then repeats as if trying to post, followed by a persistent white light that stays on, indicating a potential VGA problem. I don't think it's related to the GPU after overclocking the CPU, and even without the GPU and using the built-in graphics, it still won't post. I'm running out of ideas and really need help.
Captainchaos79 attempted using the onboard VGA but still couldn't post.
Additionally, it doesn't work even without the GPU and with the onboard graphics turned off, using the built-in graphics.
Tip: There are no onboard graphics at all. On an AM4 system, they only appear if you have an APU installed with integrated graphics, like a 2200G.
Your 2700X and other Ryzen chips without a "G" don't have any graphics. The connectors on the mainboard are just there for compatibility with APUs, not functional for regular use.
For you, they're just decorative.
Now, why do you think a failed GPU is impossible? Graphics cards can fail unexpectedly.
Reset the CMOS. This will restore the BIOS to its original settings, enabling you to save and reapply your configurations. The steps are detailed in your motherboard's manual; it seems the procedure involves swapping a jumper to another pin configuration before returning it.

Captainchaos79 shared their experience with the onboard VGA and noted that no post was made. They also mentioned that even without the GPU or using the built-in graphics, nothing appeared to post. The advice given was clear: there are no onboard graphics on an AM4 system unless an APU is installed with integrated graphics, such as a 2200G. The user pointed out that their 2700X and other Ryzen chips without a "G" also lack any graphics support. They explained that the connectors on the mainboard wouldn't work without an APU and were only there for compatibility with monitors.
The explanation continued to clarify that GPU failures are possible, even though graphics cards can malfunction unexpectedly. The user suggested considering an older working GPU or testing it on another PC as a potential solution. They also mentioned not ruling out the possibility of a faulty power supply unit (PSU) and recommended double-checking all connections between the GPU and PSU.
The advice also touched on cooling concerns, noting that fans at low speeds during overclocking aren't ideal and that high temperatures can affect stability. The user shared that adjusting fan settings in BIOS helped with consistent booting and improved performance under load. They suggested future users consider this when setting up silent overclocking.
The message concluded with empathy for the frustration caused by such issues and offered support, hoping the problem was a faulty GPU.
I attempted the onboard VGA connection, but it still didn’t post.

It’s worth noting there are absolutely no onboard graphics available. On an AM4 platform, they only function when an APU with integrated graphics is present—like a 2200G. Your 2700X and all Ryzen chips without a “G” designation lack any kind of graphics support. The connectors on the mainboard you’ve tried won’t work without the APU, serving just as a placeholder for future use.
…
Regarding your concern about a failed GPU, it’s true graphics cards can malfunction unexpectedly. I’m not suggesting this is the sole issue, but it shouldn’t be overlooked. Gaming GPUs sometimes stop working without clear reasons. If you have an older functional GPU or another machine to test it on, that could provide clarity. I wouldn’t rule out the power supply unit either, and I’d verify all connections between your GPU and PSU during your testing.

I don’t have details about your cooling configuration, but based on my experience, I no longer use low-speed fans at idle during overclocking—even if CPU temperatures are stable. Tower coolers usually aren’t enough unless you force airflow. Overclocking and voltage spikes worsen this situation. Pursuing extreme silence actually led to occasional crashes. Adjusting BIOS fan settings helped my system boot consistently, and I set AI Suite to moderate idle speeds, which improved stability under load.

I understand how challenging it can be when something breaks. Many unexpected failures happen. Best of luck—hope it’s just a faulty GPU.
Thanks for the guidance; it means a lot.
I wasn’t aware my CPU lacked built-in graphics, which is why the onboard feature didn’t activate.
You’re right about the GPU, though I suppose after a CPU overclock incident it would be unlikely. If the board were damaged, power should still reach other parts. It’s possible the motherboard itself failed, possibly affecting the PCIe slot. I’d prefer to get the unit back if it was costly, especially if it’s an Mobo model where RMA is an option.
Damn it, since I don’t have another card to try or another machine, I’ll need to send it for repair.
Thanks for the advice on cooling too. Although I’m using an NZXT H200i Mini ITX case, the heat from both CPU and GPU means I rely on NZXT water cooling for the CPU. The GPU is already water-cooled, and my CPU temperatures stayed within normal ranges—around 68°C max during testing, 40°C under load, and consistently 50°C in benchmarks.
Captainchaos79 thanks for the guidance. I wasn't aware my CPU lacked built-in graphics, which is why the onboard graphics are affected. I understand your perspective regarding the GPU, but after a CPU overclock crash it seems unlikely. If the board was damaged, power would still reach other parts. It might also be that the PCIE slot got fried. I really hope it wasn't the GPU—it would have been worth returning if it were the Mobo.
Thanks for the advice on cooling as well. Although I'm using an NZXT H200i Mini ITX case, the heat from both CPU and GPU means I've installed NZXT water cooling for the CPU and the GPU is already water-cooled. My temperatures stayed within a normal range even during overclocking—around 68°C at max, 40°C under normal use, and 50°C on the GPU. The GPU might have simply failed by coincidence. If the board was showing it was hanging up on VGA, that’s something to consider.
The GPU isn’t covered by warranty? CPUs usually don’t fail unless you push voltage too high or physically damage them. I’d say the mainboard is the most probable issue, though I’m not sure what temperature it was running at before it stopped working.
Water cooling isn’t ideal for cooling mainboard parts. If you’re cooling just the GPU and CPU in a small case, how much airflow do other components get? Especially the VRMs. Just checking GPU/CPU temperatures might miss problems. For example, a stock OEM downwind HSF cooler handles VRMs better than most high-end coolers without extra help. Water cooling is great for dense builds but you need good overall airflow—especially when adding more components.
I’m not saying this is the case, but it’s important to be aware. A 4.35Ghz all-core 24/7 overclock is quite intense for a daily driver like the 2700X. At recommended voltages (below 1.4V), only stable performance at around 4.2 was observed—of course, samples vary and some people go higher. Do you know what voltage you were running it at?
with the same length and structure:
The user expressed gratitude for the advice given. They were unaware that their CPU lacked built-in graphics, which affected the onboard graphics. They acknowledged the GPU situation but suspected a CPU overclock failure might be more likely after a crash. They wondered if the board could have been damaged, especially since replacing the motherboard would be costly. They also questioned whether the GPU was faulty and considered taking it to a repair shop. The user appreciated the tips on cooling, noting that their NZXT H200i Mini ITX case managed heat well due to water cooling for both CPU and GPU. They mentioned stable temperatures during overclocking and noted the VRMs were functioning normally. They suggested checking if the board was showing VGA hang-up as a possible cause. The user questioned whether the GPU wasn't under warranty and if the CPU had been overclocked excessively. They also discussed the importance of airflow in water cooling systems, especially for small cases, and mentioned that VRM temperatures could be overlooked if only GPU/CPU temps are monitored. Finally, they asked about methods to track VRM temperatures.
Captainchaos79 asks about checking the VRM temperatures. Possible methods include using a digital temperature probe, thermal imaging, or ensuring a fan is running to maintain a voltage below 1.4V.
Just to clarify and wrap this up for anyone facing a similar issue:
I either damaged my CPU or had bad luck with it shutting down. Either way, I was pushing it over the limit, which probably means I made a mistake. The LED on my motherboard stayed white, pointing out a VGA problem—which makes sense since without a working CPU, there’s no VGA and thus no POST. Good news, it wasn’t my expensive GPU (though I doubted that would be the case), and the CPU was still under warranty, so I sent it back for replacement.
I started using the new CPU right away. The key takeaway is avoid changing voltage while overclocking; if you do, only a minimal increase is safe—unless you’re experienced. Also, keep in mind that cooling matters a lot, even with liquid cooling. Make sure to boost fan speeds and water cooling fans to their maximum during overclocking.
